TRACK 'O'R RAIL.

SPECIFICATION forming part of Letters Patent No. 735,882, dated August 11, 1903. Application filed April30, i903. Seria1No.154,Q98. on) model.)

To all whom it may concern.-

Be it known that we, FRANCIS KEIL, a resident of New York, in the county of New York, and HENRY FRANCIS KEIL, a resident of Bronxville, in the county of Westchester and State of New York, citizens of the United States of America, have invented a certain new and useful Track onRail, of which the following is a specification.

Our invention relates to tracks or rails for slidable articles, and particularly to fastening devices used in connection therewith, and has for its object the provision of a device of the kind set forth simple in construction, inexpensive to manufacture, and which combines compactness of structure and light.

weight and also increased efficiency'in practical operation.

To attain the desired end this invention consists in the construction, arrangement, and operation of parts herein set forth.

In order to enable our invention to be fully understood, we will proceed to explain the same by reference to the drawings, in which Figure 1 represents a plan view, and Fig. 2 a side elevation, of a track made according to our invention; and Fig. 3 isa section of the same, taken on the line 3 3, Fig. 1. 1

Like letters of reference indicate like parts in all the views.

Our invention is designed to be used in connection with reciprocating articles-as, for example, sliding doors consisting of one or more leaves constructed and arranged to slide preferably in a straight line, each of said leaves being ordinarily provided with sheaves to work on a track.

Referring to the drawings, A denotes a preferably solid track or rail. At anydesired intervals a portion of each of the side faces of the said rail is punched or pressed by means of suitable machinery until an integral fiat ear Ct is formed, the said lug or ear thus constructed being formed resilient and thinner and of greater holding strength and density than the body of the rail and being provided with a polished face, which ear is also ordinarily simultaneously pierced in order to provide an approximately central orifice a. lhe ears are stamped or pressed out of the side of the body of the bar, the metal thus pressed downwardly and outwardly projecting laterally'from the bottom of the same, leaving the bar narrower at the points where the ears are pressed out. We preferably form the said ears in pairs opposite to each other, although they may be located otherwise, if desired. It

will be observed that the top face of the rail made by the above method will be of uniform height throughout.

The track may .be securely held in any desired position by suitable fastening means as, for example, the screws B.

As it is evident that many changes in the construction, form, proportion, and relative arrangement of parts might be resorted to without departingfrom the spirit and scope of our invention, we would have it understood that we do not' restrict ourselves to the particular construction and arrangement of parts shown and described, but that such changes and equivalents may be substituted therefor, and that What we claim as our invention is- As a new article of manufacture, a track or rail consisting'of a solid bar having at intervals lugs or ears stamped or pressed out of the side of the body of the bar, the metal thus pressed downwardly and outwardly projecting laterally from the bottom of the same, leaving the bar narrower at the points where the ears are pressed out, the said lugs or ears being thus formed resilient and thinner and of greater holding strength and density than the body of the rail and being provided with a polished face, the top face of the said rail being of uniform height throughout.

In testimony of the foregoing specification we do hereby sign the same, in the city of New York, county and State of New York, this 11th day of April, A. D. 1903.

FRANCIS KEIL. HENRY FRANCIS KEIL.
